Worried your kids are doing in their backs carting about the kind of homeworkladen backpacks that would fell an ox? So are Canada’s chiropractors.
Provincial associations are now recommending packs be no more than 15 per cent of a young person’s weight. In California, health concerns about burgeoning backpacks provoked the legislature into passing a law to limit textbook weights. But experts are divided.
The best advice:
■ The pack shouldn’t rise above the shoulders or fall below the hipbone.
■ Shoulder straps should be about two inches wide and padded-and both used.
■ Children less than 90 lb. should haul no more than 10 per cent of their weight.
